Title: Channel assignment method, wireless communication system employing the same, base station device, control station device and mobile station device
Inventor: WADA AZUSA
IPC: H04W92/10
Filed: 2001-09-13
Abstract: PROBLEM TO BE SOLVED: To allow a wireless base station having a plurality of channels to properly distribute traffic of each wireless channel. SOLUTION: When mobile stations 30-1 to 30-n in the wireless communication system 1 make a connection request to a base station 20 through a channel based on a mobile device number, a changeover control section 24 instructs connection of channels with less traffic to the mobile stations 30-1 to 30-n requesting the connection depending on the traffic of each channel. Thus, when only a few mobile stations exist in a communication available area of the base station 20, it is prevented that uneven traffic is caused in each channel of the base station 20 by allowing each mobile station to autonomously select the channel so as to property distribute the traffic of each channel of the base station 20.

Title: Handlebar vibration-proof device
Inventor: YONEZAWA TOMOYUKI
IPC: F16F15/08
Filed: 2001-09-19
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and mounting processes by requiring only one dynamic damper to be used as handlebars vibration-proof device without an increase in inertial moment. SOLUTION: The dynamic damper 30 is stored in a stem pipe 3 supported turnably toward a head pipe 6 and supported in an up-and-down movable manner. The dynamic damper 30 comprising a rod weight 31 and elastic members 32, 33 provided at the upper and lower ends thereof is prevented from falling down by an engagement member 37 provided on the lower elastic member 33. When body vibration is transmitted to the stem pipe 3, the vibration of the dynamic damper 30 provides a lower vibration level and precludes the transmission of the vibration to a handlebar 4 to prevent the vibration of the handlebars. The dynamic damper 30 which is arranged along the steering axis of a body center produces no increase in internal moment. Only one dynamic damper 30 to be used is, therefore, required.
